To all whom it may concern.'

Beit known that I, ALPHONSE ALEXANDRE FoIRET,a citizen of France,residing at Nice, in the Republic of France, have invented certain newand useful Improvements in Magazine-Cameras and I do hereby declare thefollowing to be a full, clear, and exact description of theinvention,such as Will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to photographic cameras which are operated by apush-button and has for its chief object to provide simple andsatisfactory means for changing the plate holders by the same motionwhich opens the shutter.

To this end the said invention consists in the construction andcombination of devices hereinafter particularly set forth and claimed.

In the accompanying drawings, Figure l represents a front View of theapparatus, the door being open. Fig. 2 represents a view partly insection, following the line 1 2 of Fig. l, showing the interiorarrangement of the apparatus. Fig. 3 represents a cross section on thelines 3-4 of Fig. 2 showing the shutter in its position of displacement.Fig. 4 represents asection on the line 5-6 of Fig. 2, showing thecontrivance by means of which the changing of plates or films isautomatically effected. Fig. 5 represents a transverse section similarto Fig. 3,showing the parts in a different position. Fig. 6 represents aside elevation of the plate carriers or supports. Fig. 7 represents aside elevation and plan of the indicator of the number of platescontained in the apparatus; and Fig. 8 represents a horizontal sectionof a part of the apparatus taken just below the top of the casing, theparts being in the position shown in Fig. 3.

This apparatus is composed of a rectanglb lar camera box a containingall the mechanism and having only the button b extending to the outside.The camera box a is divided internally into two parts by a fixedpartition e supporting the tube of the objective 7.; and the shafts ofthe shutter j and spring drum d. At the front, that is to say, at theside of the objective this box a is closed by a hinged door c and havingan opening c registering With the objective 7c. The side opposite to thedoor c is closed by a movable back f which is held in a xed position byhooks g, permitting the introduction of plates into the apparatus.Between the door c and the partition e the mechanism is located whichputs in motion a disk j serving as shutter to the objective 7c. Thismechanism is composed of a drum d having a spring Within it like that ofan ordinary alarm clock. On the periphery of this spring drum isfastened a cord e capable of being wound thereon; the other end of thiscord being fixed on a shaft f provided with a button g. On this shaft isalso fixed a ratchet Wheel having a pawl h. The shaft f, as well as thatof the spring-drum d, is journaled in the same support t'. On theprolongation f of the shaft f traversing the partition e a disk j ismounted, provided with two circular openings Z Z (Figs. 3 and 5)arranged diametrically opposite each other which in the rotation of thedisk j come alternately into position behind the objective lo to uncoverit.

The spring-drum is made ready again for Working by turning the shaftfbymeans of the button g. The cord e rolled on the exterior d of the drumunrolls itself and is wound on the shaft f, thereby rotating thespringdrum and putting the spring under strain. At the end of thisoperation, the shutter is in position and ready for the operation of theapparatus.

In order to regulate the speed of rotation of the spring-drum d at willas required, a friction brake is used consisting of a brakeshoe m,pivoting on a shaft fn. This shoe m Areceives pressure by means of aneccentric 0 provided with an arm or needle o having its point p bentback for engaging successively in the holes r. To regulate the speed ofthe barrel d and consequently of the shutter j, the arm o is depressedmore or less so that the eccentric o presses the shoe m against theperiphery of the spring-drum, producing a certain pressure on it whichdiminishes the speed of motion of the shutter.

To put this apparatus in operative position, itl sufces to arrest themovement of the shutter. For this purpose the latter is provided withtwo notches q q diametrically opposite each other. In these notches apawl s engages.

The operation of the apparatus is asV IOO follows: The door c, Fig. l,is opened, and by means of the button s the operator raises the pawl suntil the pointef it comes in contactwith the disk j,Fig. 5. lle thendepresses the button?) to disengage the shutter. The latter' turns untilits notch q engages Jthe point of pawl s which stops the said disk. Inthis position the opening Z of the disk is exactly behind the objectivek. The apparatus is then ready for a prolonged exposure. The inner faceof the shutter 7 is provided with two pairs of stops t t and t t"diametrically opposite to each other and so arranged that the stop 't isa little farther outward and farther forward than the stop t', and thestop t 1s slmilarly farther outward and farther forward than the stopt'". These stops come in contact with the receiving end of a lever Z2',Figs. 2, 3 and S, pivoted on a shaft b fixed on the partition e. Theleverb is operated from the outside by a button Z7 sliding in an openingg provided in the side wall of the case. The button ZJ is connected withthe lever b' by a rod 7L. In raising this button again lightly, thelever b is rocked, its recurved point disengages itself from the stoptand strikes against the stop t'. In this posit10n the shutter is foundready for work. In continuing to lift the buttonb the point of theleverb is disengaged from the stop t', the d1sky becomes free, turns inthe direction of the arrow, Fig. 3, and in this movement uncoversduringalonger or shorter time the ob- Jeetive 7c. The movement of theshutter is arrested by the stop t coming in contact with the recurvedpoint of the lever if.

To work the shutter again, the operator begins by pressing down thebutton l), which by means of the rod h will rock the lever b. In thismovement the point of the said lever disengages itself from the stop tand strikes against the stop Continuing to depress the button, the leverb is disengaged from the stop t", the disk j becomes free and turns asabove in the direction of the arrow. The same operation is repeatedevery time that the button b is pressed down or raised.

The lever b and rod 7L are both connected to a lever a which is mountedrigidly at its middle point on arock-shaftu. At the other end of thesaid rock-shaft another lever a is mounted similarly thereon, the twolevers moving together. Their ends m away from the rod b have twovertical bars o e attached to them, each of these bars being providedwith two feet c e. These bars move up and down with the rocking of thesaid shaft and of ciurse are operated by depressing the button As willbe seen by Figs., 3 and S, the disk 7' fixed on the shaft of drum fisheld stationary by the stops t t encounteringthe bent or recurved end ofthe lever b. lt is very easy to see that by the above simpleconstruction, to allow the rotation of the disk, it suffices todisengage the bent point or end of the lever E from either pair of thestops. The disk thus freed then turns through one hundred and eightydegrees of rotation, that is to say until the other pair ot' stopsdiametrically opposite come in contact with the said point or end of thelever. By depressing or relieving of pressure the button Z) connected tothe lever b by the rod h', I obtain the diiferent movements abovedescribed, the drum f, spring drum or barrel d and cord e, serving toturn the disk j, when the spring et the said drum CZ has been put undertension as stated and the disk is released.

Behind the pieces c u are arranged the plate carriers, the sensitizedplates resting on supports c fixed to the two opposite sides of thecase, Figs. Band rlhe two sides a; a'of each plate-carrier are providedwith two ears m- :c corresponding to the two feet /U fr of the twopieces fu c. In pressing down or raising again the pieces o 'U by meansof levers a a the feet fn fu are disengaged from the ears a," sa. Theplate-carrier, which is supported by the said feet s disengaged androcks, being pressed by a spring il applied against a plate c placedbehind the lastplatecarrier of the series. In rocking, the disengagedplate-carrier falls into the bottom r 0f the apparatus which is linedwith felt to receive it unhnrt.

The feet c fn of the pieces e o in their descending movement encounterimmediately the ears fr of the plate-carrier next following; which earsare placed lower than `those of the preceding plate carrier which isabout to fall. It is the same with the following plates, the ears otwhich are placed so that when the pieces /U r are lifted or loweredtheir feet c" t" allow the plate-carrier to escape which they hold andat the same time eneonnter the plate-carrier following.

Each plate-carrier is provided in its lower part with two eyelets ergrooves .2', through which pass rubber bands y y for holding togetherthe said plate-carriers, whioh,in rocking, open out like the leaves of abook. Between the last plate-carrier and a terminal plate c is placed asquare piece or plate f having characters on its face corresponding tothe number et plate-carriers contained in the apparatus. This squarepiece advances every time that a plate-carrier rocks and falls into thebottom of the apparatus and the numerals inscribed thereon are presentedbehind an opening g provided in the top of the case, thus allowing theoperatorto ascertain easily at any time by inspection the number ofsensitized plates or membranes remainingin the apparatus.

Having thus described my inventiomwhat l claim as new, and desire tosecure by Letters Patent, ism
